A piece of planet Mercury?
Cosmic collisions can knock pieces off planets, and these can even wander into the gravitational well of Earth. We have lunar meteorites (tektites) and some from Mars (one famous for containing structures some scientists felt showed a biological origin). This rock from Morocco, though, is apparently unique - the first piece known of the planet Mercury. Cool!
